Here, the Singaporean match fixer explains how he sets the number of goals scored over the course of a football game. He tells the players to ensure that more than four goals are scored over the course of the match, meaning that the final scoreline matters less.

The fixer, who sets out his professional relationship with convicted fixer Wilson Raj Perumal, also explains to the investigator that he pays players “about £5,000” to get a yellow card.

The footage was filmed in a series of undercover meetings in a central Manchester hotel.

Officers from the National Crime Agency held six men in the past two days, including at least three footballers and Delroy Facey, a player-turned-agent who has played in the Premier League.
